Newb needs help with spam definition

Apparently I dont know the definition of the word spamming. I thought it was someone repeatedly posting the same thing over and over with no other intention but to draw attention.
I started a thread trying to share videos and experience and information about medical cannabis equipment and concentrates. As well as reviews and things. I was hiping lots of others would add theirs also. Because some people thought it was spam when there was a whole conversation going on.
My thread was removed. So unless everyone likes your thread dont post it. For gods sake dont share a video and explain it.
Someone please explain what spamming is.... I figured the newbie section was the best place to post as it seems like a newb question.......
